ROUGH RANGE

What N501RT might be worth, and where it’s heading.

A rough range: Radar's value model doesn't cover the Cessna 500 Citation on its own yet. From Radar's listing-based estimates for business jets of similar engine thrust and age. The Embraer Phenom 300/300E curve gives the shape of the forecast, and the range is widened to match. Not an appraisal.
